Application filed November 25. 1916. Serial No 133-S25. Renewed July 31, 1919. Serial No. 314,422.

To all whom it may comer/i:

Be it known that we, JOHN ll. EVANS and FoKKo H. G. BRANDT, citizens, respectively, of the United States and Germany, and residing at Kansas City, in the county of Wya-ndotte and State of Kansas, have invented certain new and useful Improve ments in Beling-Pr sses. oi? which the following a specification.

This invention relates to billing; presses and more especially to improvements in the material folding; or tucking and retaining elements of such presses, and the object is to produce cooperating: "folding and retaining elements which will insure theproduetion of neatly finished bales.

With this general object in View, the invention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described and pointed out in the appended claims, end in order that it may be fully understood reiterence is to be had to the accompanying drawings, in which,

lleiferring now to the drewingsin which like reference characters identify corresponding parts, 1 is n. bailing press of any suitab e or preferred type and adapted to he provided with :1. suitable hopper, not

shown, from which the beling nmterizil is delivered. to the ba ling chamber. is the reciprooutory heed block or plunger for operating in the billing: chamber to compress the material into bales, and said head block is provided with e. lurality of cross grooves 3 in its front end respectively occupying the same horizontal planes as a corresponding number of openings at in opposite sides of the buling chamber or case, just rearward of the forward limit of mo *enient of the head-block or plunger, as will be noted by reference to ll 1. in which figure the plunger is indicated at the limit of its forward or power stroke, the particular nouns for operating the plunger is innnzitcrinl as regards the novel features of this invention and therefore omitted.

Arranged at opposite sides ol? the bziling ease and adapted for swinging into or out of the same through the respective openings l are fork-shaped retainers 5, said retainers being secured to the rear ends oi? a pair of horizontal swing arms 6 rirgicly secured on vertical shaft-s 7 journuled in bearings 8 secured to the heling case innny suitable manner. One of: the swing arms 6 is formed with a crank arm 9 projecting forwardly and inwardly from its respective shaft 7. The other swing arm 6 is provided with on inwerdl and rear-wardl g projecting crank arm 10 connected pivotally to crank arm 9 by a horizontal link 11, the arrangement being; such that inward or outward rotation imported to one of the swing arms, imparts like movement to the other. To impart inward movement to the swing arms and hence to the retainers 5. o crank 12 secured to the upper end of one of the shafts T, is connected to the rear end of a retractile spring: .23 connected to an adjustable hook is: mounted in o. bearing standard 15 secured upon the press. The retainers and the means for securing the some in. the balling case are echpted for cooperative relation with both types oi: folder mechanism shown and are omitted from the drawings illustratingthe modified form of folder. I

(last integral. by pre'i erei ice with the up 'withdrawn from the e ired to and depends VGE'iilCzillfC tron per bearings 8 are il Wardly projecting bearing standards 16, and jouri aled in said standards is a transverse rock shaft l7 provided With rearwardly projecting crank arms or levers 18 and a depending crank arm 19 having an outwardly projecting pin 20.

At a suit-able distance rear. 'ard tainers and at one side oi the cz j'e a euitably jou naled and driven crank 21 the same being adapted 0 ice in each revolution to effect outward inoveur it of the 'eatajiners and downward movement of the inatter deseribed. To acce suit, a lever lower end in a suitable hearing secured to the hailing e or and "with a plate 21 having" its 1 in a cam face and a fare engagement 5.; upper end of to a rod 2'" of the re or keeper :5 equi l and the i connected infitidinal bv alink 29 with the r i the cran aini 12, said crank'arni being prererahly a pin-andslot connection to Pl'OYllO to; a limited amount of play oetu'oen said link and crank arm.

The crank arin rotates in the direction indicated by the arrow Fig. l, and as the outer end of the arm passes a position ver ticallyabove its axis 03f movement, said end engages the can: face and swings the lever 22 rearward, this action as hereinbefore explained raising the lei 18 and swinging the retainers outward As the end of said crank 21 passes into engagement with the face 2 5 of plate and until it clears said :aoe, the lever 21? is retained in the position which. it was forced by the ac n oi the u on the face the lever retaining t-lllfi position he'ause the curvature oi face 26 at such time is concentric to the axis of said cam arm It will therefore be no: stood that the retainers and folder are held loaling case during the crank arm 21 upon the race 26 travel of the of lever 22.

Arranged to operate in a rertieal plane just rearward of the retainers a r eipio eatery folder o0.- In Sheet 1., the folder is CL 1 cross head 31 mounted slidingly on a vertical guide frame, said frame comp 'isin pair of vertical posts mounted in base plates 33 secured to the case and a cross be? 34 connectilm the uoner ends of the 302th o l L l The cross head 31 is provieed with end notches receiving the rear ends of levers 18, and the top oi? the baling case is pi-ovidecl with a cross slot 3Gthrougl1 Wlllfli'tlh folder operates in making its folding and return strokes, it being understood that the is pivotally mounted at its i 1 is While the crank arm 2'1. is operating: ()1 the taco 1::"1 o lever the plungu-r irulvaneed as indicated in Fin. 1. he the cm arni rides oil the lo 1' id oit' face 4o, sprin retracts and swiiigs the retainers into the case and into the rooms 3 ol the plunge:- behind the bale, 1' ac power of the spring; inoi lentally swin 'ng the lever 22 to the position shown by dotted lines l or. 1, and therefore permitting the folder to dro down through the slot 36 of the bailing case until it is arrosteo by Contact with the upper side of the phinger.

The lovers,

in this instance extend through openings 35, in the cross head 31 carrying the folder, and said cross head is provided with an upwardly projecting arm 37 in which is pivoted the front end of a link 38 pivoted at its rear end to the upwardly projecting arm 39 rigid with levers 18, said levers are also provided with a depending crank arm l0 prodded with a substantially angular slot -l-1 engaged by a roller 42 on the rear end of a rock lever mounted in a bifurcated standard n. and the front end of said rock lever is pivotally connected by a link 4:5 with the for 'ardly projectingcrank arm -6 of said levers.

/l/hen the crank arm 1.9 of transverse shaft 17 is unrestrained by the slotted rod 27, the folder drops down as before upon the plunger and when the plunger withdraws the folder continues its downward movement to substantially the position shown by full lines Fig. 7, the connections between levers 18 and link 38 through crank arin i0, rock arm 43, link 45, crank arm 46 and crank arm 39, insuring vertical downward movement of the folder. As the lever '22 is swung back to the position shown in full lines, Fig. 1, the slotted rod in'iparts rearward movement to crank arm 19 and thereby reelevates the folder and througl'i the same connections above identified the folder is caused to move vertically upward to substantially the position shown by dotted lines Fig. 7 it being noticed in this connection that Fig. 4 shows the folder in a position intermediate of its reciproeatory travel.

When the folder is nearly depressed, the roller 42 is disposed in the lower end of the angular slot 41:1. and when the folder is completely elevated said roller occupies the upper end of said slot. When the folder is about the middle of its travel the roller is at the bending point of said slot,

Fronrthe above description it will be apparent that we have produced a baline press provided with a folder which will tuck downward against the rear end of each bale all of the loose material normally forming a to l pro ection at theuppcr corner of the rem end of the halo and not secured against the some by the halting wires. and while we have illustrated and described the preferred cnil'iod monts of. the invention it'will. be apparent that it is susceptible of change in 'minor particulars without departing from i the spirit ant. scope of the appended claims.
